Maybe I should try satpc32 for tracking and Doppler, you have a private email on that subject.
Using an FT-817 for receive. Perhaps my collinear is not great for high passes but really though I should be able to hear something, and by hear I mean I have the speaker on the radio turned on Thanks for taking the time to respond, it will probably be something stupid when I figure it out (most likely the operator) Steve Daniels Amateur Radio Callsign G6UIM APRSISCE/32 Beta tester and WIKI editor http://aprsisce.wikidot.com _____ From: Rick Walter [mailto:wb3...@gmail.com] Sent: 22 November 2013 23:05 To: Steve Daniels Cc: amsat-bb@AMSAT.Org Subject: Re: [amsat-bb] FUNCUBE-1/AO-73 reception issue Ok Steve. I am listening to 145.935 MHz +/- doppler in the USB mode. The bird is using power output which is a little higher than originally planned but still lower that normal use in the future. It has a nice strong signal here. I would think you could hear it with a 1/4 wave whip or ground plane antenna on a high elevation pass. My eggbeater is only 10 feet off the ground with a large pin oak tree blocking to the south and my house blocking to the north. Hope you get to hear the bird. Let me know if I can help in any way.

Have checked the Antenna but perhaps a Tri band Co-linear antenna is not the best antenna to use. I have an interface between the radio and soundcard that I have also tested that, but I am not hearing the satellite let alone getting to decode, I did perhaps think I had got confused about the frequency and radio mode. Thanks very much for the reply though for the useful info Steve Daniels Amateur Radio Callsign G6UIM APRSISCE/32 Beta tester and WIKI editor http://aprsisce.wikidot.com _____ From: Rick Walter [mailto:wb3...@gmail.com] Sent: 22 November 2013 22:18 To: Steve Daniels Cc: amsat-bb@AMSAT.Org Subject: Re: [amsat-bb] FUNCUBE-1/AO-73 reception issue Duh! Brain fade Steve. That pass is 2:36 UTC. Also the first things I mentioned I watch are on the left bottom for the screen.

I am using a Kenwood TS 2000 X with an interface to go between the audio output in the back of the rig to the input of my HP laptop. I just have an M squared eggbeater without any pre-amp for receive. My tracking software is SatPC32 to correct for the doppler effect. I only touched up the downlink a couple of times on each of the two passes I recorded and uplinked to the warehouse (147 frames). I Load SatPC32, have it running, Load the dashboard software and choose to capture from the soundcard. The audio output of the RASCAL interface goes into the input to my sound card. I have the volume up at about 75%. Before the bird comes over the horizon, I see a wave on the Dashboard software that is the result of the noise coming from the receiver. I can actually hear the bird about 20-40 seconds before it comes over the horizon (very faint but hear the distinct tone). The real time screen starts filling with data as I see on the right bottom counting of the type of data received, the serial number, and to the right, the packets decoded and missed, plus the number of packets already sent to the warehouse and the number waiting to be sent. Don't know if that helps at all. Having taught Earth Science and Astronomy for 36 years, now retired, I not only like the linear transponders, but love to collect telemetry from the birds too. It is not available yet, but I can't wait until they allow us to download the whole earth orbit data from the warehouse. I want to watch the data change as the bird goes around the earth. I used to do that with UO-11 telemetry and use the data for labs using Excel's graphing functions in my Astronomy classes with my students. Did you try decoding the sample wave files they provide? They allow you to experiment getting the audio to your soundcard, then to the dashboard software. I'm looking forward to the 03:41 Z pass for me later tonight.

I seem to have the correct keps as I see station near me uploading. Am using a radio not a dongle 145.935MHz USB mode is what I am using as settings.
